FASTENER FOR SAFETY CALK WEBS,

Application filed April 9,

This invention relates generally to antiskid devices and refers moreparticularly to fastening means for detachably securing anti-skiddevices upon vehicle wheels.

An object of the present invention is to provide a fastener foranti-skid devices which is simple in construction, economical tomanufacture and which may be easily and quickly actuated in removing andapply ing the anti-skid device to a vehicle wheel.

With the above and other objects inl view the invention consists incertain novel features of construction, combinations and arrangements ofparts as will bemore fully described and particularly pointed out in theappended claims.

In the drawings:

Figure l is a view showing my fastener applied to an anti-skid device; n

Figure 2 is an enlarged perspective View of the fastener in closedposition together with the cable attaching plate;

Figure 3 is a view of the fastener in open position;

Figure lis a perspective view of the permanent fastener;

Figure 5 is a sectional view of the fastener shown in Figure 4; and

Figure 6 is an edge view of the cable attaching plate. y Y

Referring now to the drawings and particularly to Figure 1 there isshownan antiskid device comprising a safety calk web 1 composed of aflexible materialsuch as rubber and being provided upon its outersurface with transverse. and longitudinal calks 2 and 3 respectivelywhich are. so arranged as to prevent skidding in different directions.This safety web is adapted to encircle a vehicle wheel and is providedwith side cables e and 5 respectively attached at spaced intervals tothe web in any suitable manner.

1n applying the web to a vehicle wheel, it is only necessary to providemeans for detachablv connecting the end portions of one of the cablesand the end portions of the cable 4 are 'therefore permanently securedtogether in a manner to be hereinafter described, I The cable 5 hasinserted therein a which is provided at one end with a housing 1928.Serial No. 268,651.

8 adapted to receive and to securely clamp thereto one end of the cable5. `To the other end of the body member is pivotally connected a lever 9provided intermediate its ends with a hook portion 10, said leverbeingadapted in its closed position to lie in close proximity to thebody member and having its end portion 11 extending beyond the housing 8as clearly shown in Figure 2. l

To the other end of the cable 5 is secured a link member 12 providedwith a housing engage the hook of the endy portion 11 of theA leverforretaining the parts in closed position. 1t will be noted that thehookportion of the lever is positioned lto one side of the pivot point 17 sothat when the parts are in the position shown in Figure 2, there will bea tendency for the link member 12 to exert a pull upon the levei' whichwill be transmitted tothe end portion thereof and will tend to effect abinding actionV between the end of the lever, the cable, and the link1G, thereby preventing this link from slipping off the end of the lever.Because of the construction of the link member 12 this pull against thelever will be effective both when the curved portion is in engagementwith the pivot point 17, and when the link member is moved laterallythereof away from the body member during the rotation of the vehiclewheel. Tt is therefore apparent that the lever will be securely held inclosed position and that the parts willv be retained in the positionshown in Figure 2 regardless of the movement of the link member relativeto the lever and body member.

The means for clamping the ends of the cable in the housings S and 13 issubstantially the same. l'n eachv instance 'the housing is pro-videdwith a cap or cover 18 provided with a downwardly extending slottedflange 19. The end wall 20 of each housing is also provided with a slotadapted to align with the slot of the coverfor receiving the cable andabove.

permittingthe end to pass Within the housing. A scievv 2l is adapted toextend transveisely of the housing and to engage both the cover and thebase of the housing, for

clamping these two parts together and at the same time clamping theendportion of the cable between the slotted portions mentioned To furthersecure each cableendto its respective fastener element itis bent upon4itself toforniv an eye through which the screw 21 is adaptedto extend.This provides-an eihcient means for `securing the members 7 `and l2 totheir respective ends ofthe cable.V

VIngremoving and applying the anti-skid device to a wheel it isnecessary to 'provide lniea'ns for permitting theend of the cable towhich the link member is secured, to become suiliciently disengaged fromthe Web 1 to prevent any binding'of the parts during either of theseoperations. Fortaking care of thisthere isjprovided a plate QQsuitablysecured ,by means of links 23 to the Web. The'end of this plateisformed'into a pair of inwardly curved prongs 24 and 25 respectivelythrough which the cable is adapted to pass. The

prong fterminates Short of the body of the plate While the prong 25 isextended past the Abody but spaced therefrom.` The arrange- -ment issuch that when the cableris taut it Will be securely retained inoperative posi- Vtion by the plate in a manner similar tothe usualfasteners 26; However when the cable is slack it can be easilydisengaged from the 'plate by first slipping it` out of the'loop formedby the :prong 24' and thentwisting it out of theloop formed by thepronUQ. Likewise in applying the device the ca le may be inserted firstintothe loop formed by the prong 25 and then into the loop formed by theprongQfi andiwhen the link member is secured in' place and the cableistaut the plate will function to prevent disengagement of the cabletherefrom.

For securing the endiportions' of the cable 4c together there isprovided a housing 27 having its'endwalls slotted in a manner similar tothe Walls of .the housings 8 and 13. A cap 28 is provided with slottedend flanges 29 which cooperate With the end Walls ofthe 4housingtoposition the cable ends in the saine manneras that described above.:Screws 30 -are provided for drawing the housing and cap together toclamp the cable ends there-` betiveenand theseen ds are also providedwith eyes through which the screws extend for additionally securing theendsin place. t t

xIt Willibe lnotedthat:vvhenthe lever is inv closed 'position theend ofthe hook portion V10isiinclose proximity to theV end wall Vof thehousing -8 so that thereivill be no possi i bility of the loop portionof the link member `beceiiiing disengaged from the, hook portion.

-This is .an Vadded .safety feature Vpresent, due

to the novel arrangement ofthe 'several ele-v`iimentsrelativetoeneanether. y

From the foregoing,rit will be` apparent that I have provided animproved form of -a fastening means for an anti-skid devi ce' which iseasily and quickly actuated forfastening the device in operativeposition and for removing the same from a vehicle Wheel.

y lVhile it is believed that from the foregoing 'descriptiom'the natureand advantages of the invention will be readily apparent, I desire tohave it understood that I do not limit my self to what is herein Vshownand described and that such changes'may be resorted'to when desired asfall Within the scope ofwhat is claimed. i V
